The traditional graph-based personal recommendation algorithms mainly depend the user-item model to construct a bipartite graph. However, the traditional algorithms have low efficiency, because the matrix of the algorithms is sparse and it cost lots of time to compute the similarity between...

In this paper, we focus on attacks based on sniffing like MitM, and how to counter them from the network layer perspective. We've already developed an algorithm called pathfinder that allows us to forward segments from same packets via different paths. Doing so, we'll ensure that an attacker...

Recent attacks against critical infrastructures have shown that it is possible to take down an entire infrastructure by targeting only a few of its components. To prevent or minimize the effects of this kind of attacks, it is necessary to identify these critical components whose disruption,...

Alzheimer's disease (AD) is a progressive brain disorder which has a long preclinical phase. The beta-amyloid plaques and tangles in the brain are considered as the main pathological causes. Functional connectivity is typically examined in capturing brain network dynamics in AD. A definitive...

Public streams of geo-located social media information have provided researchers with a rich source of information from which to draw patterns of urban-scale human-mobility. However, most of the literature relies on assumptions over the spatial distribution of this data (e.g., by considering...

The article addresses some fundamental values in education and their implications in the Nordic countries, such as equity, democracy, social justice and inclusion, while its main aim is to introduce and discuss main findings from case studies in pre-, compulsory and upper secondary schools that...

This paper focuses on the potential use of visual research for the study of the social and solidarity economy, by presenting some of the methodological insights and challenges that arise for the use of video research in the study of such initiatives reflecting on the authors experience of the...
